Context-Engineering

In 2025, METR — an AI safety and capability research organization — ran a rigorous randomized controlled trial. Sixteen experienced open-source developers worked on 246 real-world tasks, each randomly assigned to either use AI coding tools freely or not at all. The result was counterintuitive: developers using AI tools were 19% slower on complex tasks. Before the study, those same developers predicted AI would make them 24% faster. After completing the experiment — still believing they had gone faster — their subjective confidence remained completely unshaken. ...

The Biggest Shift in 2026: Context Over Phrasing If you have been writing prompts by carefully choosing words and hoping the model “gets it,” you are operating on a 2024 mental model. In 2026, the industry consensus is clear: the quality of the context you assemble matters far more than the phrasing of your instructions. This shift has a name: Context Engineering. What Is Context Engineering? Context Engineering is the discipline of designing systems that assemble the right information into the model’s context window at the right time. ...
